  1. ITU/WMO Seminar on: Use of Radio Spectrum for Meteorology: Weather, Water and Climate Monitoring and Prediction Geneva, 16-18 September 2009 ITU Radiocommunication Standardization Activities Kevin HUGHES Chief of ITU-R Study Group Department E-mail: kevin.hughes@itu.int

  2. Presentation • Objectives of ITU-R Study Groups • Structure of Study Groups • Radiocommunication Assembly • Scope of Study Groups • Some key areas of standardization • ITU-R Recommendations, Reports and Handbooks

  3. Role of ITU-R • ensure the rational, equitable, efficient and economical use of the radio-frequency spectrum by all radiocommunication services, including those using the geostationary-satellite or other satellite orbits,… • carry out studies without limit of frequency range and adopting Recommendations on radiocommunication matters. (ref. Article 12 of Constitution)

  4. Role of ITU-R Role conducted through (inter alia): • World (and Regional) Radiocommunication Conferences • Approval of Recommendations by Member States Technical studies are required which are conducted inStudy Groups

  5. Principal Tasks of ITU-R Study Groups Develop technical bases for WRCs (and RRCs) e.g. CPM process for WRCs Develop Recommendations • International voluntaryStandards on: • spectrum management, satellite orbits, frequency sharing • system characteristics and operation ITU-R represents: International focal point for the standardization of wireless systems Compile Reports and Handbooks

  17. Current key priorities in ITU-R Standardizationinclude: • Emergency communications • Environmental monitoring

  18. EmergencyCommunications Prediction and Detection: Meteorological services (Met-Aids, Met-Sat); Earth Exploration Satellite Service Alerting: Amateur service; Broadcasting services (terrestrial and satellite); fixed services (terrestrial and satellite); Mobile services (land, satellite, maritime) Damage assessment and Relief:Amateur service; Broadcasting services (terrestrial and satellite); fixed services (terrestrial and satellite); Mobile services (land, satellite, maritime); Earth Exploration Satellite Service Regulatory role Standardization role

  19. EmergencyCommunications • Databases relating to safety of life and rescue operations • available frequencies for use in emergency situations and guidelines on the management of radiocommunications (Res 647 (WRC-07), Res ITU-R 53) • Maritime mobile Access and retrieval System (MARS) • Regionally Harmonized Frequency Bands for Public Protection and Disaster Relief • preferred frequency bands listed in Res 646 (WRC-03) • Study Group activities • spectrum management guidelines • Recommendations, Reports, Handbooks providing technical basis for development and operation of the radiocommunication services used in the various phases of emergency and disaster situations

  20. Climate change • ITU-R’s standardization role on monitoring and mitigating the effects of climate change is very closely linked with that on Emergency Communications • Through its responsibility for international spectrum management, ITU-R provides interference-free spectrum and satellite orbits for climate monitoring • Cooperates with UN agencies (e.g. WMO) and international and national organizations involved with climate change

  21. Climate change • Study Groups develop Recommendations, Reports and Handbooks on • operation of radio systems for environmental monitoring, including climate change; e.g. ITU/WMO Handbook on “Use of Radio spectrum for meteorology: weather, water and climate monitoring and prediction” • facilitating the introduction and operation of low-energy systems; e.g. analogue to digital broadcasting • Satellite-based remote sensors (passive and active) are main tools for obtaining environmental data for climate monitoring • Systems belonging to • Earth exploration satellite service • Meteorological-satellite service • Meteorological aids service form backbone of the WMO Global Climate Observing System
